Add local fork of meteor-reactive-cache package

- Clone @wekanteam/meteor-reactive-cache to npm-packages/
- Add .meteorignore to exclude npm-packages from Meteor
- Update package.json to use local file path

This allows direct modification of the package for Meteor 3.0
async migration while maintaining publishability to npm.

+Utilities for caching reactive data
+
+### Installation
+````bash
+  $ npm install --save meteor-reactive-cache
+````
+
+### Usage
+
+#### `ReactiveCache(compare: function)`
+A simple reactive cache. It haves the same API like a `ReactiveDict`, but the values are getting deleted if all wrapped computations are stopped.
+
+````es6
+import { Tracker } from 'meteor/tracker'
+import { ReactiveCache } from 'meteor-reactive-cache'
+
+const reactiveCache = new ReactiveCache(/* compareFn */);
+reactiveCache.set('foo', 'bar');
+const computation = Tracker.autorun(() => {
+  reactiveCache.get('foo'); // reactive!
+})
+reactiveCache.set('foo', 'new bar');
+computation.stop(); // keys will be invalidated if they don't have reactive dependants
+reactiveCache.get('foo'); // undefined
+````
+
+#### `DataCache(resolve: function, { timeout: number, compare: function })`
+Provides a simple reactive data cache, by passing in a function, that resolves a key to data in a reactive context.
+
+````es6
+import { Tracker } from 'meteor/tracker'
+import { DataCache } from 'meteor-reactive-cache'
+
+const dataCache = new DataCache((key) => {
+  // do some expensive reactive work here, which returns the same data for the same key.
+  // this function will only be executed if a reactive dependency changes or the requested key isn't cached.
+
+})
+const computation = Tracker.autorun(() => {
+  reactiveCache.get('foo'); // reactive!
+})
+computation.stop(); // keys will be invalidated if they don't have reactive dependants
+reactiveCache.get('foo'); // undefined
+````
+
+#### `reactiveField(resolve: function, { timeout: number, compare: function })`
+Like DataCache, but with a much simpler API and support for multiple function parameters.
+
+````es6
+import { Tracker } from 'meteor/tracker'
+import { reactiveField } from 'meteor-reactive-cache'
+
+const field = reactiveField((val1, val2, val3) => {
+  // …
+})
+const computation = Tracker.autorun(() => {
+  field('foo', 'bar', 1234); // reactive!
+})
